Patent 7326771 was granted and assigned to Monterey Bay Aquarium Research Institute (Mbari) on February, 2008 by the United States Patent and Trademark Office.
Two long-wavelength fluorescent proteins isolated from the strawberry anemone, Corynactis californica are provided. These proteins are homologous to known fluorescent proteins, but their unique properties, including yellow or red color of emission, can find use in replacing and supplementing known fluorescent proteins. In addition, because of their longer wavelength absorption and emission spectra, they can be used in energy transfer applications with the known shorter wavelength fluorescent proteins and non-proteinaceous fluorescers.
